Abstract

L'invention concerne une structure de châssis à déformation progressive comprenant un élément structural (50) et un élément de déformation progressive de la structure de châssis. La structure à déformation progressive comprend au moins une zone (57) à absorption d'énergie disposée à l'intérieur de l'élément structural. A son tour, l'élément structural se déforme de façon progressive lorsqu'il est soumis à des charges d'une grandeur inférieure à la charge nécessaire à la déformation plastique du reste d'un élément structural au moins. L'invention concerne également un procédé de fabrication d'une structure de châssis.
